Aurora

Long-standing space mystery revealed - origin of the 'theta aurora'

Auroras are the most visible manifestation of the Sun’s effect on Earth, but many aspects of these spectacular displays are still poorly understood. Thanks to ESA’s Cluster and NASA’s Image satellites working together, a particular type of very high-la

Dynamic auroras visible for the fifth day in a row

For the 5th day in a row a crack in the Earth's magnetosphere is allowing solar wind to reach Earth. Although a full geomagnetic storm is not required to generate auroras at this time of the year, coronal hole effects and multiple solar sector changes currently affe

Geomagnetic storm in progress, auroras visible at high latitudes

Plasma cloud unleashed by M-class solar flare on August 22 reached our planed early Wednesday, August 27. Wind speeds increased from near 280 km/s to 340 km/s while density remained primarily between 5-10 p/cc (protons per cubic centimeter).Active to minor storm (G1) co

Geomagnetic storm reached G2 levels, amazing auroras photographed from ISS

A Coronal Mass Ejection (CME) unleashed by solar filament eruption on August 15 started interacting with Earth's magnetic field around 07:00 UTC on August 19 causing, at first, only a minor instability.As the Earth passed through the plasma cloud the effects in

Flight of the Aurora - Time-lapse video by InFocus Imagery

On June 5, 2014, a giant filament erupted on the Sun. It released a Coronal Mass Ejection (CME) which left the Sun at 1.2 million mph (512 km/s). Although majority of plasma cloud was directed away from Earth we were still hit by a small part, a glancing blow.The i

Geomagnetic storming in progress, bright auroras formed around the Arctic Circle

During the late hours of April 11 the Interplanetary Magnetic Field (IMF) tipped south and opened a crack in Earth's magnetosphere. Our planet is now under the influence of coronal hole high speed stream (CH HSS). CH HSS effects are expected to begin subsiding

Near X-class solar flare and geomagnetic storm - M9.3

Near X-class solar flare reaching M9.3 erupted from departing Sunspot 1996 on March 12, 2013 at 22:34 UTC. This decaying sunspot is located near eastern limb and generated CME was not geoeffective, however, it produced a R2 (Moderate) Solar Flare Radio Blackout

Aurora borealis photographed in Slovenia, rare blue aurora in Norway

Aurora borealis is a normal event at high latitudes during geomagnetic storms but when they are seen as low as Slovenia (Zagarjev vrh, N46.03, E14.65) you know the event is rare and stunning for the observers. The following image was captured in Slovenia on

Subsiding geomagnetic storm sparked bright auroras over northern Europe, Greenland and Iceland

Coronal mass Ejection brushed Earth's magnetic field causing G2 (Moderate) Geomagnetic Storming late on February 27, 2014. The event was associated with the R3 (Strong) Solar Flare Radio Blackout event caused by February 25th X4.9 solar flare. A

Genesis of a Lunar Halo - Time-lapse video by InFocus Imagery

This short time-lapse was captured on February 19, 2014. At approximately 02:00 UTC an unexpected CME (Coronal Mass Ejection) impacted our planet's magnetosphere. The aurora display was fairly active peaking at G2 storm levels. A large portion of the display

Cassini gets a 360-degree view of Saturn's auroras

While Hubble Space Telescope, orbiting around Earth, was able to observe the Saturn's northern auroras in ultraviolet wavelengths, Cassini spacecraft, orbiting around Saturn, got complementary close-up views in infrared, visible-light and ultraviolet

Sky Dance - Time-lapse video by InFocus Imagery

Found a little bit of Aurora on Februaty 8/9, 2014. There was a very subdued show. Conditions on Friday were blowing snow, -22 deg C with a 15 km/h wind from the north. I thought that was pretty cold until I headed out again on Saturday night when it was crystal clear

Solar activity increased again - M5.2 from central region on the Sun

Region 1967 (S13W12, Fkc/beta-gamma-delta) produced three moderate solar flares in last couple of hours. M3.8 was detected at 01:23 UTC, followed by M1.2 at 03:06 UTC and an impulsive M5.2 at 04:00 UTC. This region is almost directly facing our planet,

10 M-class solar flares erupted in last 2 days, all from one big region

In last 2 days, since it announced its comeback to Earth view on January 27, Region 1967 (S15E60, Fkc/beta-gamma-delta / formerly known as Region 1944) produced 10 M-class solar flares. Current location of the region is not favorable for Earth directed

Auroral Tempest - Time-lapse video by InFocus Imagery

This time-lapse was captured on the morning of November 11, 2013. It is suspected that two CMEs (Coronal Mass Ejections) on November 8th and 10th from two separate X-class solar flares combined to form one cloud of plasma. The interaction of this energy with

Elemental Iceland - stunning timelapse video by Stian Rekdal

Norwegian photographer Stian Rekdal drove nearly 5 500 kilometers on his last month's trip to Iceland and took over 40 000 photos on the way. 3 500 of them were used to create this showcase of Iceland's natural beauty. The glacier lagoon

Six years of observing the Earth's magnetosphere

There is still only a handful of spacecraft to watch for solar and magnetic storms but the number of observatories has been growing over the last six years. Today, these spacecraft have begun to provide the first multipoint measurements to better understand space

Solar wind stream buffers Earth magnetic field

Earth is currently inside a solar wind stream flowing in from the massive coronal hole on the Sun's northern hemisphere. Elevated solar wind speed (above 600 km/s) combined with a south tilting Bz component of Interplanetary magnetic field (IMF) is responsible
